Opening trap

A prepared line that punishes a natural-looking but mistaken reply.

An opening trap lays a tempting path — a free pawn, an 'obvious' developing move — that runs into a concrete refutation. Many famous traps (the Légal, the Noah's Ark, the Elephant) have caught even strong players.

Traps are double-edged: a trap that's declined often leaves the trapper slightly worse, so the best ones are simply good moves that also punish a mistake.

Why it matters

Knowing the common traps in your openings keeps you from falling into them — and lets you set them when the opponent goes wrong.

The mistake everyone makes

Playing a dubious move purely hoping for the trap, and ending up worse when the opponent finds the simple, good reply.
